HRS launches scraped surface heat exchanger

HRS has launched a scraped surface heat exchanger called the HRS-Rotex. The HRS-Rotex is a rotary scraped surface heat exchanger and utilises a multi-tube design that increases the capacity per module.

Another feature of the HRS-Rotex is a helical screw design on the scraper system. This helical screw helps to push the product forward during operation and helps to reduce pumping costs when a system operates with the HRS-Rotex system.

In addition, HRS has taken a new approach to the service side of the heat exchanger and has implemented a baffle design to increase fluid velocities and further boost heat transfer.

Marcos Alarcon, chief designer at HRS Heat Exchanger’s comments, “Great thought has gone into the HRS-Rotex concept. We have spent many hours analysing existing rotary scraped surface heat exchange technology, identifying shortcomings and have engineered new solutions. We believe that the HRS-Rotex concept that has come out of this process will help our customer reduce their capital and operational expenditure for difficult heat transfer applications.”

Matt Hale, international sales manager at HRS Heat Exchangers says, “The HRS-Rotex is complementary technology to the other scraped surface technology we offer – the HRS Unicus. We have come to realise that the HRS Unicus is the ideal technology for evaporation of fouling liquids and large duty heat exchange applications with difficult fluids. However, for smaller duties involving high viscosities and fouling problems, the new HRS-Rotex technology provides a better solution towards efficient heat exchange. The combination of both technologies positions HRS Heat Exchangers in a unique way. For any type of application where scraped surface heat exchangers are needed, we bring the optimised solution being able to pick from multiple technologies”.
